Abstract
A data processing apparatus includes an input unit which inputs a code train through a transmission path, including a plurality of parity codes, each of which is constructed by a plurality of data. An error processing section corrects error codes by using the parity codes supplied from the input section, and a counter counts the number of correction processes executed by the error processing section. A selecting section selects an error correction mode of the error processing section in accordance with an output of the counting section, among a plurality of modes including first and second modes having different error correcting capabilities.
